PostgreSQL 11 Administration Cookbook

Getting ready

You'll need to get operating system access to the database system, which is what we call the platform on which the database runs.

The server log can be in a few different places, so let's list all of them first so that we can locate the log or decide where we want it to be placed:

• The server log may be in a directory beneath the data directory.
• It may be in a directory elsewhere on the filesystem.
• It may be redirected to syslog.
• There may be no server log at all. In this case, it's time to add a log soon.

If not redirected to syslog, the server log consists of one or more files. You can change the names of these files, so it may not always be the same on every system.
